DS1250W-200 Datasheet
The first byte sent to the CAT5259 from the master/ processor is called the Slave/DPP Address Byte. The most significant four bits of the slave address are a device type identifier. These bits for the CAT5259 are fixed at 0101[B] (refer to Table l).

The K, B, and T grades are guaranteed for maximum nonlinear- ity of+l/2 LSB. For these grades, this means that an analog value that falls exactly in the center of a given code width will result in the correct digital output code. Values nearer the upper or lower transition of the code width may produce the next upper or lower digital output code. The J and A grades are guaranteed to +1 LSB max error. For these grades, an analog value that falls within a given code width will result in either the correct code for that region or either adjacent one.

The formula below calculates the approximate inductor value to be used for an inverting charge pump regulator using the LT1617. As for the boost inductor selection, a larger or smaller value can be used. For designs with varying VIN such as battery powered applications, use the minimum VIN value in the equation below.
